The gear element has a central gear element region. A first membrane is affixed to a surface of the first body frame, the membrane covering the chamber and having an annular aperture enclosing a central region of the membrane that is affixed to the central gear element region of the gear element. The disclosed force transfer device can be axle or shaft based. Also disclosed in a micro electrostatic motor that includes a motor body having a first and a second face, the motor body defining a chamber and a rotor having a central region. A membrane is disposed over the first face of the motor body, the membrane supporting a pair of spaced electrodes that are electrically isolated by a gap, the membrane having an annular aperture that defines a central region of the membrane that is coupled to the central region of the rotor.

Abstract: Disclosed is a micro electrostatic motor that includes a body having a first and a second face and having a chamber. A first membrane is disposed over the first face of the body and a rotatable disk is disposed in the circular chamber about a member. The disk is disposed in the circular chamber and is free to rotate about the member. The disk has on a first surface thereof a set of three mutually electrically isolated electrodes, with each of the electrodes having a tab portion and being electrically isolated from the member. A second membrane is disposed over the second face of the body and a pair of spaced electrodes are provided on portions of the second membrane, with the pair of spaced electrodes being isolated by a gap between the pair of electrodes. A cylindrical shaped member is disposed in the chamber electrically isolated from the three mutually electrically isolated electrodes on the disc.
